We have constructed a system for building 3D kinematic models (shape, body part segmentation, and joint information) of humans. This system is based on our temporal shape-from-silhouette algorithms. An overview of the system is as follows:

An example of the results of applying the system is the three kinematic models illustrated in the following movie.

These kinematic models can then be used to track new motions of the person using a tracking algorithm closely related to our temporal shape-from-silhouette
algorithms. Examples of tracking the person in this way are shown below.
